The Las Vegas energy-efficient home upgrade company that starts where the heat gets in.
Most valley homes don't need everything — they need the right two or three upgrades in the right order. We start with the building envelope: windows and doors first, then the mechanical system that has been oversized to compensate for them.

Order of operations matters more than product brand
A lot of Las Vegas homeowners get sold a new air conditioner while their west-facing glass is still pouring radiant heat into the living room. The new system runs quieter and the bill barely moves, because the load never changed.
Fix the envelope first. Once solar heat gain and air leakage are under control, the cooling load drops — and any mechanical upgrade after that can be right-sized instead of brute-forced.
That sequencing is the whole reason we lead with windows and doors, and it's why our assessment starts with a walk-through instead of a price sheet.
Upgrades we install, in the order we recommend them
1. Replacement windows
Triple-pane, Low-E, desert-rated glass. The single biggest lever on a Las Vegas cooling bill — typically 20-40%.
2. Entry & patio doors
Foam-core insulated slabs and Low-E sliders that stop the leak you can feel with your hand.
3. High-efficiency HVAC
Right-sized systems specified after the envelope is fixed, so you buy the tonnage you actually need.
4. Roofing & attic
Roof repair or replacement to protect the envelope work underneath it.

Why Las Vegas homeowners choose us
We never subcontract — ever
100% W-2 veteran-led employees. The national window companies sell the job and hand it to subcontracted crews; the team that measures your openings is the team that installs them, and the only company on the hook is us.
Double lifetime warranty
Materials and our workmanship, covered for as long as you own the home. Not prorated.
Built for the Mojave
Glass packages and frames specified for 115° summers and relentless UV — not a national spec sheet.
Honest, same-day pricing
One visit, one written price, no four-hour pitch and no 'today only' pressure discounts.
Permits and HOA handled
We pull Clark County permits and prepare HOA architectural submittals for you.
Energy math, not guesses
We model your cooling load so you know what the upgrade should save before you buy.
Frequently asked questions
How much does window replacement cost in Las Vegas?+
Most Las Vegas window replacement projects land between $650 and $1,200 per window installed, depending on size, frame type, and glass package. A typical 10-window single-story home runs roughly $7,500-$12,000. We give you a written, itemized price at the assessment — no vague ranges and no surprise change orders.
How much can new windows lower my power bill?+
Homeowners replacing single-pane or failed dual-pane windows in the Las Vegas Valley commonly see cooling costs drop 20-40%. The savings come from Low-E coatings rejecting solar heat gain, argon-filled chambers slowing conduction, and a proper air seal ending infiltration.
How long does installation take?+
Most whole-home window projects are installed in one day. Larger homes or jobs needing stucco or frame repair may take two. We give you an exact schedule window and show up in it.
Do your windows qualify for tax credits or rebates?+
Our ENERGY STAR® qualifying packages are commonly eligible for federal efficiency credits, and some NV Energy programs apply as well. We provide the manufacturer certification paperwork your tax preparer needs.
Do you replace the whole window or just the glass?+
Both. If the frame is sound and only the seal failed, glass-only replacement is often the smarter spend. If the frame is warped, leaking, or single-pane, full-frame replacement is the only fix that actually lowers your bill. We tell you which one you need.
What warranty comes with the windows?+
A double lifetime warranty: the manufacturer covers materials and glass seals, and we cover our installation labor for as long as you own the home. Not prorated, and it transfers on a documented sale.
Do you handle HOA approval?+
Yes. We prepare the architectural submittal packet with product specs, frame colors, and elevation notes so your HOA approval goes through without a second round.
